Thanks for writing here.
From the information you are having either scabeis.
Since you have already been to dermatologist
,it will be better to continue the treatment.Only thing is apply permite cream to whole body a single application.Apply full cream at one time only and do not leave any area.This will kill itch mite but itching will still persist for 10 to 15 days for which you need to continue other medicines.
Hope this will help you.Take care.
